Brooks Koepka is one of the longest players on the PGA Tour. In 2015, he averaged 308.2 yards off the tee, good enough for eighth overall in driving distance. In 2014, he ranked sixth overall. The guy can crush it. Listed at 6 feet tall and weighing 186 pounds, Koepka isn't as tall as Bubba Watson or Dustin Johnson, but he still generates massive amounts of clubhead speed (122 mph, ranked fourth overall) with his driver. We asked his coach, Claude Harmon III, to offer four tips that you can steal in order to gain extra yards with the driver. It's all in the power backswing.
1. DO LESS, GET MORE
Brooks proves that you don't have to swing past parallel to hit it 300 yards. In fact, overswinging saps speed, because it requires extra hand and arm manipulation to square the face. Halt your backswing when the muscles in your back say "stop." You want a "tight" feel at the top, not a loose one.
2. SHOW SOME SPINE
Don't just turn your shoulders in your backswing—turn your entire back. Try to get your spine to face the target, as Brooks does here. If you do it without overrotating your lower body, you'll add yards fast.
3. THE JOY OF FLEX
His knee flex is the same as at address. Maintaining your posture like this makes it easy to catch the ball on the sweet spot, where maximum energy transfer occurs. Keep your chest the same distance from the ball from start to impact. You'll pound it every time.
4. PLANT YOUR STANCE
Sure, he's about to pulverize it, but Brooks's feet are flat on the ground. Excess shifting and rolling of the feet can limit your power push-off. Hit practice balls flat-footed— you'll feel a huge difference
